(Pump Return)
2)
OA3 Connection of control signal for alternative heat source
with On/Off signal with mains voltage
(Output Alternative)
Function: volt free NO contact, max. 230 V AC/10 W
1) Terminal assignment: 43 – position of buffer cylinder (A);
44 – position of bypass (B)
2) Terminals: 15-16
Table 5
The assignment of the electrical connection depends on which system is
installed. A suggested procedure for establishing the electrical
connection is described in Figs. 9 to 16 at the end of this document.
▶ Only use electric cables of the same quality.
▶ Make sure the power supply is connected to the correct phases.
A power supply via an earthed safety plug is not permissible.
▶ Connect only components and assemblies to the outputs as
described in these instructions. Do not connect any additional
controls that operate other system components.
The maximum power consumption of the connected components and
assemblies must not exceed the power output stated in the
specifications for the module.
▶ If the mains voltage is not supplied via the electronic system of the
heat source: install a standard all-pole isolator (in accordance with
EN 60335-1) on site to interrupt the mains voltage.
▶ Route cables through the grommets, connect them as shown in the
connection diagrams and secure them with the strain relief devices
included in the scope of delivery ( Fig. 9 to 16 at the end of this
document).

Connection diagrams with system schematics

The hydraulic diagrams are only schematic in nature and are non-binding
suggestions for a hydraulic layout. The safety equipment must be
implemented in accordance with the applicable standards and local
regulations. For further information and options, refer to the technical
guides or tender specification.
